Output Quality Settings

When converting JPG to PDF, pay attention to:

• Image compression: High-quality PDFs preserve JPG at its original quality. Some tools re-compress and reduce quality.
• Page size: “Fit to page” vs. “Actual size” — “Fit to page” scales the image to fill the paper; “Actual size” uses the image’s pixel dimensions.
• Orientation: Auto-detect portrait/landscape based on image dimensions.

For the best results, use our converter which preserves original image quality without re-encoding.
